Initially purchased iPhone 11 Pro Case Friendly screen protector and later discovered the full-coverage screen protector provides 2 more millimeters of coverage and perfectly and fully covers the screen within my Mous Contour case. This said, the molding of the included plastic installation guide was less ergonomically designed than the guide included with the case friendly package, and, both were still not *pitch perfect*, or perfectly form fitting enough, in order to snap them over the phone and usefully use them to fit them just right so it wouldn't overlap or press into the Mous case. I took almost 30 attempts at eyeballing the ear piece cut with a direct overhead lighting reflection bouncing off the gap between the edge of the earpiece cut out and the iPhone's glass curve around the earpiece, and even then, after I saw I had *pitch perfectly* given equal distance of the screen protector cut out around the ear mic, when I eyeballed the perimeter of all 4 sides I found that when you look at how the screen protector lays on top of the iPhone screen, the sides were perfect but the screen protector was not fully flush at the bottom of the phone by half a millimeter but the top edge of the screen protector stopped just at where the screen of the iPhone begins to curve. This means the ear mic cut out is not perfectly aligned to sit above an below the ear mic cut out by half a millimeter and still not visibly show it is not flush with the bottom edge of the iPhone's curve. All things considered... the screenprotector has about half a millimeter overhang at the top and bottom edge no matter how *perfectly* you eyeball it (and I'm someone who's able to see half a millimeter deviations just with plain sight). But even without it, if you're going to market a version of a given screen protector model and tell potential customers that it works with so-and-so cases, BUT not mention it needs to be installed with insane coordination abilities or it will lift off of the phone screen with play/usage in the case, then you absolutely must upgrade and refine the specs of your screen protector AND invest in super form-fitting installation trays that are actually useful. All in all, given the price, the quality, and my half-millimeter critiquing, and as long as there aren't any useage issue going forward (I *just* installed it) then I say FloLab screen protectors are a SOLID 4.5/5
